In the previous post, I outlined some Arduino code to generate tide height predictions for a NOAA tidal reference station.

Now let’s do something useful with this newfound functionality. In the experiments I run, it’s useful to keep intertidal animals like snails and limpets on a natural tidal cycle. In addition, some animals like high-shore limpets really dislike being continuously submerged, and will crawl up out of the tank and die when they dry out. In this case, I built a “limpet splasher” system that sprays water in the aquarium for a few seconds at a time with pauses in … Continue Reading
